Phaseolin type, determined by one-dimensional sodium dodecyl sulfate polyacrylamide gel electrophoresis, was used to suggest dissemination routes of common bean (Thaseolus vulgaris) cultivars from their areas of domestication to Europe and Africa. In the Iberian Peninsula, ‘C’ was the most frequent phaseolin type. Only in Chile has a comparably high ‘C’ frequency been observed previously, indicating that many Iberian cultivars may have been introduced from Chile, or that many Chilean cultivars may have come from the Iberian Peninsula. In Europe (outside the Iberian Peninsula), most cultivars exhibited a ‘T’ type. The high frequency of this type may be related to the high frequency of green pod cultivars among European cultivars. Most African cultivars exhibited a ‘T’ or a ‘C’ type and may have been introduced from Brazil, the Iberian Peninsula, or western Europe. ‘T’ or ‘C’ cultivars had larger seeds than ‘S’ cultivars. The phaseolin patterns of cultivars with different seed types and of early French cultivars are discussed.
